Qhia: Dihydrogen yog npaj hauv chav kuaj los ntawm tshuaj tiv thaiv zinc nrog rau dilute sulfuric acid lossis hydrogen chloride. Hauv ob qho tib si cov tshuaj tiv thaiv zinc yog oxidized. Zinc sulphate yog tsim thiab dihydrogen yog tsim.
Dihydrogen khaws cia li cas?
Dihydrogen ntawm siab purity feem ntau yog tau los ntawm electrolysis ntawm dejnyob rau hauv muaj me me ntawm cov kua qaub los yog lub hauv paus. Thaum lub sij hawm electrolysis, dihydrogen yog sau ntawm cathode thaum dioxygen yog liberated ntawm anode.
Leej twg npaj H2 thawj zaug kuaj?
Hydrogen gas, H2, yog thawj zaug tsim los ntawm Phillip von Hohenheim (lub npe hu ua Paracelsus, Daim duab 2.1. 2. 1) los ntawm kev sib xyaw hlau nrog cov kua qaub muaj zog. Nws tsis paub tias cov pa hluav taws xob uas tsim los ntawm cov tshuaj tiv thaiv no yog cov tshuaj lom neeg tshiab.
Dihydrogen npaj ua lag luam li cas?
Kev Lag Luam Kev Lag Luam ntawm Dihydrogen
Los ntawm chav (txoj kab txoj kev) super-heated chav yog dhau los ntawm cov hlau filings rhuab mus txog 1023-1073 k thaum hydrogen tsim. Cov ntshiab ntshiab (> 99.95%) dihydrogen yog tau los ntawm electrolyzing sov aqueous barium hydroxide tov ntawm npib tsib xee electrodes.
Yuav ua li cas dihydrogen npaj los ntawm dej los ntawm kev siv tus neeg txo qis?
Dihydrogen yog npaj los ntawm reacting a high reacting metal like sodium with water. …2Nas+2H2Ol(Cold) →2NaOHaq+H2(g) b.
